Brand: SanDisk
SKU: SDSDUP-016G-A46

Overview

The SanDisk Ultra 16GB SDHC Memory Card (SDSDUP-016G-A46) is designed for everyday photography and video recording in compatible digital cameras, camcorders, and other SDHC devices. Rated at Class 10 and UHS-I, it provides a minimum sustained write speed of 10MB/s, which is sufficient for capturing Full HD 1080p video and burst-mode photography. Read speeds of up to 48MB/s help keep file transfers to a computer or other device moving at a reasonable pace.

With 16GB of storage, this card is best suited for users who shoot casually and offload files regularly rather than those who need extended capacity for long sessions. It is a practical choice as a backup card or for use in secondary devices where high-speed performance is less critical. The standard SD form factor ensures broad compatibility across cameras, laptops, and USB card readers without the need for adapters.
